Looking for aftermarket pistons and rods for my 6.0, but i cant find anywhere that sells them, a few here and there, but i would like to know of a website that has piston choices listed, that arent 1000 for a set, does gm offer stock pistons in overbore sizes? thanks

 

Texas Speed, SDPC, Speed Engineering, West Coast Cylinder Heads..... They should be able to get you lined out...

 

I would look to one of the companies already mentioned plus others for a set of forged pieces, but also to answer your question, GM does offer an Hypereutectic LS2/LQ9 replacement piston available in a 0.020" oversize. It is listed under part number 89017479, however it does require a floating wristpin rod as would be found in an LS2 or LQ9. It is advertized as offering 10.9:1 compression ration with 65cc heads.
